Usage

From source file:com.workday.autoparse.json.parser.JsonParserUtils.java

/**
 * Parse an array that has only non-array children into a {@link Collection}.
 *
 * @param reader The reader to use, whose next token should either be {@link JsonToken#NULL} or
 * {@link JsonToken#BEGIN_ARRAY}.//www  . j a  v a 2  s . c  o m
 * @param collection The Collection to populate. The parametrization should match {@code
 * typeClass}.
 * @param itemParser The parser to use for items of the array. May be null.
 * @param typeClass The type of items to expect in the array. May not be null, but may be
 * Object.class.
 * @param key The key corresponding to the current value. This is used to make more useful error
 * messages.
